UNITED STATES JAMES W. MANN, OF BROGKVILLE, ONTARIO, CANADA.

ASEEDING-MACHINJE.

SPECIFICATION forming part of Letters Patent No. 263,188, dated August22, 18 82.

Application filed December 1, 1881. (Model.)

.To all whom it may concern:

ing-Machines; and I do hereby declare that the following is a full,clear, and exact description of the same.

The invention relates to improvements on my seed-hopper patented June15, 1880, and

has for its object to simplify the construction and lessen the cost ofmanufacture. I

Figure 1 is a longitudinal section of part of my improved seed-hopper.Fig. 2 is a transverse section of the same. Fig. 3 is a top view.

A is the seed-hopper.

B B are sectional castings fitting together endwise by lapped joints,and secured to the sides of the hopper by screws or other fastenin gs,and form an internal bottom to the hopper. The castings B B have adownward slope toward the seed-aperture in the longitudinal direction ofthe hopper and semicircular transversely. The sections B at one end arecast with aneye, U, in a semicircular recess at the top of the slope,said eyes bearing the agitator-shaft D, and at the other end of thesection is formed a concavity, R, to admit of the endwise insertion ofthe shaft into the eye, said shaft carrying the agitator-wheels E, asdescribed in my former patent. The castings B are flat on the outsidearound the seed-apertures, and have downward lugs F in rectangularposition, which serve the purpose of keeping in place the castings Grand slide 0, hereinafter referred to. The exterior bottom of the hopperis composed of sectional castings G and blocks of wood I, which fitbetween the castings, and are secured to the bottom edge of the hopperby screws or other means. The castings have ribs J J, between which isthe hole through which the seed descends. The ribs bear against the flatoutside surface or bottom of the castings B, and prevent escape of seedexcept through the seed-apertures. The castings G on the outside areprovided with a fiat slide, K, running in boxed grooves or guides. Theslides have a hole through which the seed passes, said hole having acollar, L, to which the seed-tubes are secured, whereby the seedtubes,with the slide K attached, are independently removable from castings G,so as to permit of an interchangement of tubes adapted for eitherdrilling or scattering.

N is a button on the end of castings G, to secure the slide in position.By means of these slides a change of scattering and drill tubes can bemade.

0 is a flat slide extending the whole length of the hopper, and isperforated at distances to correspond tothe seed-apertures in thehopper. The slide operates .between the lugs F of castings B and theribs J of castings G. The ribs are notched to receive the slide by whichthe seed-apertures are opened and closed by the usual endwise movement.

I? are bars crossing the bottom of the hopper above the wood blocks I,levelwith the fiat face of the castings B, and serve as intermediatebearings for the slide. Said bars are cast with lugs Q to guide theslide, and are fixedly secured to the bottom edge of the hopper.

I do not broadly claim a hopper-bottom composed of sectional castingshaving seed-apertures and placed endwise together; but

I claim as my inventionl. A seed sower hopper having an internal bottomcomposed of sectional castings B, fitting endwise together, each sectioncast integrally to fit against the inner side of the hopper, the upperface formed of inclined sides sloping longitudinally of the hoppertoward the seed-aperture, and graduated to a semicircular curvetransversely, and having a half-round recess at both ends, and asemicircular eye over said recesses at one or both ends, for receivingthe agitator-shaft, as set forth.

2. In a seed-hopper, an internal bottom composed of sectional castingsB, fitting endwise together, each having downwardly-converging sideslongitudinally of the hopper, an eye 0 in a recess at one end, and aconcavity, R, at the other end for the reception of the agitator-shaftD, as set forth.

3. In a seed-hopper, the seed-tubes removably attached to the bottom ofthe hopper by a sliding and locking connection consisting substantiallyof casting G, fixed to the hopper, slide K, carrying the seed-tube, andbutton N, locking said slide in its seat in casting G, whereby tubes toeither scatter or drill can be interchangeably applied, as set forth.
